The purpose of this study is to examine the relationship between MI and web-based learning in elementary school English education. For this purpose, this paper first examined MI and instructional models of web-based learning, which was based on constructivism. In order to verify the effects of this experiment, we proposed a web-based English learning and teaching model and applied it to the 5th grade students in an elementary school. After the experiment, we analyzed the effects that MI affects students' English achievement. The results of the study were as followings. First, students' intrapersonal intelligence, linguistic intelligence, musical intelligence, and spatial intelligence had a positive effect to their English achievement. Second, bodily-kinesthetic intelligence, logical-mathematical intelligence, and interpersonal intelligence did not have a positive effect on their English achievement. This study indicates that all kinds of multiple intelligences should be thoroughly considered when we design and practice web-based English learning and teaching models.
